Superscript Two Symbol Meaning
Superscript two (²) is a punctuation character that represents the number 2 when it’s written in a raised form. The most common purpose is exponent-style writing, like indicating “squared” after a term (e.g., x²). It can also appear in compact labels and typography where space matters, such as “m²” for square meters or “A²” in informal formulas. In plain text, using ² helps keep the visual meaning without needing a full superscript layout. In HTML or CSS, you can insert it directly as the character (²) or by Unicode escapes, depending on your environment.
Common uses
- •Writing exponents in plain text, such as x²
- •Labeling areas like “m²” for square meters
- •Expressing “squared” notation in notes, comments, and documents
- •Creating compact measurements (e.g., cm²) in UI text
